Patient discussion about solution

Q. WHAT ARE THE CAUSES N SOLUTION TO PNEMONIA? I HAVE A FRIEND WITH THIS DISEASES WHAT SUGGESTION CAN I GET FROM U AND TELL TO MY FRIEND I WILL BE WAITNG FOR YOUR SUGGESTION.

A. Pneumonia is an infectious disease of the lungs, and is caused by various bacteria, viruses or fungal infections. The most common pneumonia is caused by viruses, and the treatment is usually symptomatic (anti caugh and fever, etc.), however, because there are many bacterias that can cause it as well, you should recommend to your friend to go see a doctor and get some antibiotic medications.

Q. Can you suggest an immediate solution for this, please? My niece is 22 years old. She was very excited about being a single mother. She was staying with her boyfriend when she announced that she was pregnant. About 5 weeks of pregnancy she had a fight with her boyfriend that ended up in him shoving her. She fell violently to the ground. She is complaining of spotting and cramps. I am worried if anything has gone wrong. Can you suggest an immediate solution for this, please?

A. I want to add, that the physical act of violence done to her and the unborn child might have been criminal assault. If she or the unborn child were harmed, she could file charges. There is no excuse for the boyfriend's irresponsible behavior. If she is in any danger from this guy doing this again, she could seek help at a shelter for battered women, or even better staying with someone in her family.

Q. Type 2 Diabetics solution My uncle is suffering from type 2 diabetics and i want to know that
is there any permanent solution for type 2 diabities. Very worried about weight loss too. Any one there to give us a permanent solution?

A. Type 2 diabetes is due to improper use of insulin or insulin resistance.
